Question

An insect 4.00 mm tall is placed 25.0 cm to the left of a thin planoconvex lens. The left surface of this lens is flat, the right surface has a radius of curvature of magnitude 12.1 cm , and the index of refraction of the lens material is 1.70.

Explanation / Answer

Power P = (n-1)*(1/0.121 -0)

= (1.7-1)* (1/0.121 -0) = 5.785

by using lens formula,

1/o +1/i = 1/f

1/0.25 + 1/i = 5.785

1/i = 5.785-4 = 1.785

i = 1/1.785 = 0.56m = 56 cm

b) y' = y*i/o

= 4*56/25

= 8.96 mm.
